Bombshell! 100,000 People Secretly Tracked Through Their Cell Phones

Oh my. I can imagine the calls for Congressional hearings and impeachment will resound across the nation.

Oh wait. Never mind. It was some university researchers from Massachusetts doing it, so it must be OK.
Researchers secretly tracked the locations of 100,000 people outside the United States through their cell phone use and concluded that most people rarely stray more than a few miles from home.

The first-of-its-kind study by Northeastern University raises privacy and ethical questions for its monitoring methods, which would be illegal in the United States.

It also yielded somewhat surprising results that reveal how little people move around in their daily lives. Nearly three-quarters of those studied mainly stayed within a 20-mile-wide circle for half a year.

The scientists would not disclose where the study was done, only describing the location as an industrialized nation.

Researchers used cell phone towers to track individuals' locations whenever they made or received phone calls and text messages over six months. In a second set of records, researchers took another 206 cell phones that had tracking devices in them and got records for their locations every two hours over a week's time period.

The study was based on cell phone records from a private company, whose name also was not disclosed.

Study co-author Cesar Hidalgo, a physics researcher at Northeastern, said he and his colleagues didn't know the individual phone numbers because they were disguised into "ugly" 26-digit-and-letter codes.
The idea that even a single terror suspect has his calls tracked normally sends the left into apoplectic rage.

It'll be curious to see the reaction in this case.
Barabasi said he did not check with any ethics panel. Had he done so, he might have gotten an earful, suggested bioethicist Arthur Caplan at the University of Pennsylvania.

"There is plenty going on here that sets off ethical alarm bells about privacy and trustworthiness," Caplan said.

Studies done on normal behavior at public places is "fair game for researchers" as long as no one can figure out identities, Caplan said in an e-mail.

"So if I fight at a soccer match or walk through 30th Street train station in Philly, I can be studied," Caplan wrote. "But my cell phone is not public. My cell phone is personal. Tracking it and thus its owner is an active intrusion into personal privacy."
